Since it seems that true intermediate caliber rounds are up and coming(6.5-6.8) Why hasnt anyone just chopped a regular .308/7.62 NATO cartridge?

Size it so it will fit in an AR platform(or similar), seems like it would be a good round IMO, I could go for it, more so than a Grendal or a SPC

Whats does the ammo experts think?

Hornady already beat you to it, though it is meant for leverguns.

DAMN!

Is it short enough to fit in an AR mag?



A .308 lever gun!...Brilliant!

Good point! As soon as they make an AR that takes AK mags(no franken mags) thats affordable or when CProducts make their 7.62x39 mags work Ill be all over it

I've always thought the .243 had alot of military potential.  Is there a possibility that a .308 with a 100 or 110 grain bullet could be practical?

But that's .310!

The main problem with the M43 cartridge is the bullet. Short, fat bullet with poor ballistic coefficient, and hardly any bearing surface resulting in minute of barn accuracy.

Do you understand all the disadvantages of doing this?

6.8 SPC was developed with a number of important goals in mind, but one of them was maximizing terminal ballistic performance without sacrificing accuracy.  As such, it is far more accurate than, say, 7.62x39, plus it does more damage, has a flatter trajectory, feeds better in 5.56-based weapons, the magazine holds more ammo, the ammo is lighter, has less recoil, is more controlable in full-auto, and so on.

What possible advantage would there be to your idea?

That was the point I was trying to make, for those slow on the uptake.

And the same goes for the 243 idea. whenever I hear people wanting to do this I can't figure out why they would want a 308 case necked down to take a smaller bullet.  Why not just stick with the 308?  I have never had anyone answer me on that one.

I'm just gonna theorize that its a search for more velocity and a flatter trajectory

By the way.....308x1.5 Barnes was developed in the very early 1960s. Look it up.

How does having a smaller diameter bullet make it more accurate?? Or do you just mean that because american companies are loading it?

Which is why I'm waffling on the 6.8.  After the zombies/plague there will be a lot of 7.62 and 5.56 ammo laying around for the taking from cold dead hands.  I'd love to love the 6.8, and after I get an upper maybe I will, but ammo for it becomes the limiting factor.

The 7.62x39 and many other cartridges have a bad reputation for accuracy because of the platform they are most commonly used in. The same cartridges on a good platform are usually as accurate as the next. Also some factory ammo isn't loaded with accuracy as a criteria because of the perceived use of the ammo.
